Building a better shrimp nursery, part 2

Shrimp nursery systems offer the shrimp industry an important opportunity to increase profits, by helping produce strong, healthy and uniform juveniles with significant potential for compensatory growth after their transfer for final pond grow-out. Biofloc technology and water quality are 


Understanding the oxygen demand of aquafeeds

Manufactured aquafeeds, if improperly managed, can result in undesirable oxygen demand that can reduce dissolved oxygen levels and pollution through effluents, and stress cultured animals.

Proper water circulation in aquaculture ponds, Part 2

Promoting water circulation during the day time is an effective strategy to enrich pond water with oxygen produced by photosynthesis, and can significantly reduce the costs of night time supplemental aeration. Many types of effective, commercial water circulators are available.

Proper water circulation in aquaculture ponds critical

Many aquaculture ponds require mechanical aeration both for increasing dissolved oxygen levels and to promote mixing of oxygen-rich and oxygen-depleted waters, which also helps prevent turnover. Promoting water circulation during the day time is an effective strategy to enrich pond 


The importance of water analysis in aquaculture

Proper monitoring of water quality in aquaculture production systems is critical to enable appropriate and timely management decisions. It requires reliable equipment, trained technicians that follow instructions and apply quality control measures, proper reagents and calibrated equipment, and appropriately collected
